Abstract
AbstractThe copolymerization of norbornene (NB) and divinylbenzene (DVB) was carried out using anilinonaphthoquinone‐ligated nickel complexes of the type [Ni(C10H5O2NAr)(Ph)(PPh3)] (1a: Ar = C6H3‐2,6‐ iPr; 1b: Ar = C6H2‐2,4,6‐Me; 1c: Ar = C6H5) with modified methylaluminoxane (MMAO) as a cocatalyst. The DVB content was varied (5–25 mol%) and the resulting copolymers exhibited number‐average molecular weights (Mn) of 40,000–69,000 g/mol with polydispersities (PDI = 1.5–1.8). The styryl group of the NB/DVB copolymer was used for grafting poly(methyl methacrylate) by reverse atom transfer radical polymerization using azobisisobutyronitrile in the presence of copper chloride and bipyridine.
